Formation Damage

Definitions of formation damage
Why prevent damage?
Major mechanisms of formation damage
Mechanical Damage Mechanism
- Fines migration
- External solids invasion
- Water injection issues associated with suspended solids
- Phase trapping basics (relative perm induced damage)
- Issues affecting phase trapping (water, oil and gas based)
- Diagnosing phase trapping effects in different reservoirs
- Retrograde condensate reservoirs and dropout effects
- Reducing/Removing water blocking issues
- Removing condensate blocks
- Geomechanical damage issues
- Perforation induced damage
- Glazing and Mashing (drill bit and drill string induced damage)
Chemical damage mechanisms
- Rock – Fluid issues
  - Clay swelling
  - Clay defloculation
  - Adsorption
  - Dissolution
Fluid – Fluid Issues
- Emulsions
- Scales
- Precipitates
- Paraffin (wax) problems
- Asphaltenes
- Other organic solids
Wettability Alterations and their impact on reservoir performance
Biological formation damage issues
Thermally induced formation damage
- Mineral dissolution
- Reprecipitation
- Mineral transformations
- Wettability alterations
- Lab testing for thermal damage
Formation damage and horizontal wells
Why is damage more a concern in horizontal wells

Dr. Brant Bennion, P.Eng has over 25 years of experience in the area of multiphase flow in porous media, formation damage, phase behavior, drilling, completion and enhanced oil recovery operations. Brant has been a distinguished lecturer for both the SPE and the Petroleum Society on the topic of formation damage, lectures as an adjunct Professor at the University of Calgary, is the author/co-author of almost 250 technical papers and has lectured extensively in over 40 countries in recent years. He is currently serving as member of the Editorial Review Board for the Journal of Canadian Petroleum Technology. He has been employed at Hycal Energy Research Laboratories in various capacities since 1979 and currently is the direction of the flow in porous media group. He is a registered Professional Engineer with APEGGA and holds BSc. and Ph.D degrees in Chemical and Petroleum engineering from the University of Calgary.
